Abstract: LOCK OFF-LOCK ON                Abstract of the Disclosure A lock off-lock on for a handle of an electric circuit breaker includes a unitary metallic member having a first handle engaging portion adapted to be inserted into an opening of a circuit breaker handle.  The opening can be provided in a direction perpendicular to the reciprocating movement path of the handle between "on" and "off" positions.  The member includes a second handle engaging portion joined to the first portion by a bight to form a U-shaped structure.  The second handle engaging portion engages a surface of the handle which is in exposed adjacency to a dependent arcuate portion which is in proximal relationship with the interior of a slot in the housing in which the handle outwardly extends.  A flat spring, coupled to a part of one side of the second portion by an angular bend,  is  engageable with the dependent arcuate portion and is in abutting relationship with the housing at one of the edges of the slot.  A flange is coupled to the flat spring proximal to the bight and is bent outwardly away from the housing so as to facilitate removal of the lock off-lock on from the handle.   The handle engaging portion includes  flash piercing means at a free end of the portion.

Title: Gravity - magnetic ore separators
Inventor: MARTINEZ EDWARD
IPC: B03B7/00
Filed: 1983-06-29
Granted: 1987-10-20
Abstract: GRAVITY - MAGNETIC ORE SEPARATORS A gravity-magnetic ore separator for concentrating magnetic or weakly magnetic minerals having a relatively high specific gravity is disclosed. The ore separator utilizes codirectional magnetic and gravitational forces to achieve separation capabilities in excess of that which can be achieved using gravity forces alone. Typically, the gravity-magnetic ore separator is formed by retrofitting a conventional gravity separator such as a spiral, cone, pinched sluice, etc. with magnets so as to enhance the separation capability of the conventional gravitational ore separator. Means are provided to prevent build up of magnetic material on the surface over which the ore flows.

In accordance with a first preferred embodi-ment, the first and second compounds are first separately prepared from their respective constit-uent elements.  The first and second compounds are then combined and heated to form a melt.  There-after, the melt is cooled to solid material form and then crushed to form the particulate mixture.     In accordance with a second preferred embodi-ment, a melt is first formed from the second com-pound and the constituent elements of the first compound.  The melt is then cooled to solid mate-rial form and then crushed to form the particulate mixture.     In accordance with a further embodiment of the present invention, the first and second com-pounds are first separately prepared from their respective constituent elements and then separate-ly crushed into particulate form prior to forming the particulate mixture.

Abstract: ABSTRACT        A safety valve is disclosed which may be in-stalled on an offshore wellhead above the tubing head and below the Christmas tree.  The valve has a housing with upper and lower vertical passages and a lateral housing passage.  A cylindrical gate is disposed with-in the lateral passage and includes a "T" shaped pas-sage therein.  The gate may be moved laterally and angularly within the lateral passage.         During completion or workover of the well, the gate is moved laterally until the upper and lower vertical passages are in full open communication to run drills, hangers or other large diameter devices into the well via a BOP which may be attached to the top of the housing.         During normal production, the gate may be laterally moved into the intersection of the vertical and lateral passages and the small through head part of the "T" passage serves to provide a vertical flow path through the production bore which is sealed off from the larger upper and lower vertical passages. Flow through side outlets in the housing is possible through the base of the "T" passage.  The gate maybe angularly moved to have production to the lateral outlets via the head part of the "T" when the base part of the "T" is aligned with production tubing.         Should the need arise, the valve may be angularly rotated to a position where the fluid flow path of the production tubing is completely shut in.         This abstract of the disclosure is neither intended to define the scope of the invention, which is measured by the claims, nor is it intended to limit the invention in any way.
